ELECTRONIC WARFARE ENVIRONMENT MODEL.
Source publication
Aiming education and research in electronic warfare (EW), the Brazilian Air Force acquired an electronic warfare training system. Its operation integrated with tools of Virtual Instrumentation (VI) has didactic potential to be explored either in local or remote laboratory courses. The Work in Progress presented in this paper has as objectives to st...

... Equation (1) is valid when the target is illuminated by a plane wave. This condition is satisfied by the far-field approximation, i.e., when the object is located at a distance at least r = 2D 2 /λ, where D is the largest dimension of the object, and λ is the wavelength of the radar [7]. Note that the calculation of scattered fields from a target using (1) is complex; analytical solutions of this equation exist only for objects with simple geometries. ...
... The radar setup is based on the Lab-Volt Radar Training System, which has been described in detail elsewhere [1,7]. This system consists of six interconnected subsystems that allow training on analog and digital aspects of radar operation, radar tracking, electronic warfare, radar antenna steering, and radar cross section. ...
In order to improve the understanding of radar technology, and especially the interpretation of radar cross section (RCS) data by undergraduate students, we developed a study where the RCS of objects having simple and complex geometries were obtained using a simulation software tool and a radar training system consisting of an inverse synthetic aperture radar designed to operate at close range in an academic laboratory or classroom environment. The comparison of results obtained by both methods demonstrated the advantage of using simulations and experiments to interpret RCS data. Moreover, the simulations provided the students with an important visual information, and the radar operation allowed the students valuable hands-on experience with rather sophisticated equipment.
